The color scheme is much better now. The old was way too contrasty. One of Edward Tufte's rules for multiple items in a single composition -- like multiple posts in a forum window -- is to use the smallest effective difference. The way the forum works now, with alternate entries shaded, is better than, for example, lines between each entry, as the shading makes for a less intrusive boundry. But that's only true if the shading is subtle. When the forum went to the current look, that shading was far too strong for my taste. Today it looks much better.
I'm assuming this is a conscious choice, and if so well done. The white colors of the website now match the magazine much better than yellow did, which is something. (Except what's with the button bar to the right of the main logo at the top of this page? Where did those colors come from?)
By the way, everyone interested in web design should read the work of Edward Tufte. Besides, he has a whole chapter in Visual Explanations on how magicians use the techniques of visual representation for the opposite of their normal purpose, co-written by Jamy Ian Swiss. It includes Richard's infamous six-finger salute to Ed Mishell.
